FODDER-CUTTER.

SPECIFICATION forming part of Letters Patent No. 562,513, dated. June23, 1896. Application filed August 7, 1895. Serial No. 558,478. (Nomodel.)

To all whom it may concern:

Be it known that I, JOSEPH DICK, a citizen of the United States, and aresident of (Jan ton, county of Stark, State of Ohio, have invented anew and useful Improvement in Fodder-Outters, of which the following isa full, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification.

My invention relates to an improvement in fodder-cutters; and itconsists in providing means whereby the movable cutting-blade may beadjusted bodily to or from the stationary cutter or by which either endof the movable cutter may be adjusted to or from the stationary cutter.

My invention further relates to and consists in providing means wherebythe feedgage plate may be secured in desired relation to both thestationary and the movable cutter.

IVith these objects in view my invention relates to certain features ofconstruction and combination of parts, as will be hereinafter describedand claimed. Figure 1 of the drawings isa perspective of the end portionof a fodder-cutter, showing my invention. Fig. 2 is a cross -sectionthrough the hub of the gage-plate and its support. Fig. 3 is alongitudinal section through Fig. 2 from 00 to 00. Figs. 4 and 5 aredisks by which the movable cutter and gage are adjusted to the fixedcutter. Fig. 0 is a detail longitudinal section showing thestationaryand vibrating knives.

The invention is especially adapted for a hand field and hand cuttingmachine of the kind shown in Fig. 1 of the drawings.

A denotes a cast-metal end piece for the feed-box B, having an arm, asO, projected therefrom, on which is supported the axis, about which thecutting blade or knife K is rotated. In the rear face of the arm 0 isprovided a recess a, in which is placed a rotatable disk E, having onits rear face inclined surfaces b, against which is placed a similarnon-rotatable disk F, having corresponding engaging graded or inclinedsurfaces c, and on the rear side of said disk is provided a circular orconcaved depression h, having in its face oppositely and horizontallydisposed grooves or recesses h. There is also provided on the rear faceof the arm 0 a lug, as d, and on the disk F lugs e, that engage the lugd, by which the disk F is held against rotation.

The grooves h in the rear face of the disk F are provided to receive theribs j on the front end of the conical sleeve G, which is of the form,or substantially so, shown in Fig.

3. The front or large end of saidsleeve is I adapted to have its axis ofmotion adjustable to throw the point of the knife farther in or outrelatively to the stationary knife, the ribs j resting in the grooves72/ for the purpose hereinafter stated.

On the frame or plate J, that carries the movable knife K, and integraltherewith, is provided a sleeve portion L, having external ribs in, Z,and m, on which is secured the head portion M of the gage-plate N, saidhead having grooves a and 0, to receive the ribs Z and m, and in thehead M is provided a setscrew 19, by which the head is secured on thesleeve.

In operation, the parts being assembled as shown in Fig. 3, to adjustthe movable cutter K with respect to the stationary knife P (shownthrough the broken-away portion in the frame J) the nut g on thetightening-bolt is turned back a distance, and the disk E rotated in itshearing or socket a in the arm 0. The grades I), resting against thegrades 0 on the face of the disk F, will move the sleeves G and L andthe cutter K parallel from or to the stationary or fixed cutter P, inwhich position or desired adjustment the parts may be secured by thebolt II, and to adjust the end portions of the knife K to the fixedknife P, the sleeve G may be rocked or moved laterally on its bearing onthe disk F. In use the natural wear of the parts is such as to allow theend 'of the knife K next the handle Q to leave the knife P and pass downwithout cutting all of the straw or other fodder, and to bring the knifeK hack into operative position the thimble may be moved on the disk F tobring the cutting edges of the two knives into desired alinement, orwhat is preferable, to set the handle end of the knife K a little closerto or tighter on the knife P than the other or heel end, as in use thetendency of the handle end of the knife K is to spring back from theknife I.

In practice, as heretofore constructed, it has been found difficult tohold the gage-plate securely on the sleeve L, and to remedy thisdifficulty I have provided on the sleeve ribs, as land m, thefirst-mentioned having parallel sides, and the latter converging sides,as shown, and in the head M corresponding grooves 11 and 0, by which thehead M is guided along the sleeve and the gage-plate oscilated Withoutgreat strain on the set-screw p, by which the gage-plate is held indesirable adjustment relative to the fixed knife.

Having thus fully described the nature and the object of my invention,what I claim is- 1. In a fodder-cutter of the character described, thecombination with the fodder-box, the stationary knife, the arm securedto said box, and the screw-bolt secured thereto provided with atightening-nut, of the rotatable disk carried by said bolt. havingcam-faces 011 one side, the non-rotatable disk having correspondingeam-faces engaging therewith, the sleeve through which said bolt looselypasses, the rotatable sleeve mounted thereon, and the arm and knifesecured thereto, substantially as described.

2. The combination in a fodder-cutter of a fixed, and a vibratorycutter, of the disk F, having on its rear face, a concaved socket havingtherein oppositely-disposed grooves, a cutter-supporting sleeve having aconical bore, and ribs adapted to said grooves, and a through-bolt,whereby the vibratable cutter may be adjusted transversely to a linedrawn longitudinally through the fodder-box, substant-iall y asdescribed and for the purpose set forth.

3. The combination in the described foddercutter, having a fixed and avibratory cutter, and a gage-plate that moves with the lastmentionedcutter of the ribs Z and m, on the supporting-sleeve L, the rib, Z,having parallel sides and the rib, 777., having converging sides head M,and grooves n and o, to receive the ribs Z and m, and a set-screw 19,whereby said head may be secured in desired adjustment on the. sleeve Lwithout great strain on the set-screw, substantially as described andfor the purpose set forth.

4. In a fodder-cutter of the character described, the combination withthe fodder-box, the stationary knife, the arm secured to said box, thescrew-bolt connected therewith and its nut, of the rotatable disk havingcam-faces on one side, the non-rotatable disk having cam-faces on oneside engaging therewith and formed with a concave recess on the oppositeside provided with opposite grooves,the sleeve through which said boltloosely passes having its inner end convexed and provided wit-h ribsengaging with said grooves, and the rotatable sleeve provided with anarm and knife, substantially as described.

5. In a fodder-cutter of the character described, the combination withthe fodder-box, the stationary knife, the arm secured to said boX andprovided with a stud or lug and a circular recess, of the screw-boltsecured to said arm, the tightening-nut, the rotatable disk having a hubon one side engaging with said recess, and cam-faces on its oppositeside,

the non-rotatable disk having a lug engaging with the lug of said armand provided on one side with cam-faces engaging with the camfaces ofthe rotatable disk and formed 011 its opposite face with a concavedepression provided with opposite grooves, the sleeve through which saidbolt loosely passes having its inner end conveXed and formed with ribsengaging with said grooves, the rotatable sleeve mounted on said sleeveand provided with an arm and the knife secured thereto, substantially asdescribed.

In testimony whereof I have hereunto set my hand this 27th day of July,A. D. 1895.
